Honeywell second geneartion smart valves
a Generation III valve. If you could give me some numbers of the valve I may be able to steer you toward some help.
What makes you think it is the valve? If it is Intermittent Ignition it is probably a SV9540 or SV9640 verson. Make sure someone has tested the microamp circuit before condeming the valve. Give me some details on its behavior and I may be able to save you some money.All of these use a Q3400A Igniter/Sensor so it just may be a problem with the sensor needing cleaned or replaced.
Most of the Generation III valves are OEM only valves so you will probably have to go to your local Heil dealer for a part or go on-line to their web site.
